EV Range Calculator — Convert Between Standards
Every standard (WLTP, EPA, CLTC, NEDC, JC08) measures range under different conditions. Convert values between standards and find out how certified range differs and what to expect in winter.

Why does EV range differ by standard?
EV manufacturers test range under different conditions — speed, temperature, air conditioning, driving style. Therefore CLTC (China) typically shows the highest values, while EPA (USA) is the most conservative and closest to real-world range. WLTP is the European compromise that replaced the older NEDC standard in 2017.
🇪🇺 WLTP — European Standard
Valid in the EU since 2017. Tests at speeds of 10–130 km/h, includes urban and motorway driving. More realistic than the older NEDC, but still optimistic compared to everyday use — real range is typically 10–20 % lower.
🇺🇸 EPA — US Standard
The most conservative of the world standards. EPA values are approximately 20–30 % lower than WLTP. Closest to real-world everyday range — if a car meets EPA, it rarely disappoints in reality.
🇨🇳 CLTC and NEDC — Optimistic Standards
CLTC tests at lower speeds — results are typically 15–20 % higher than WLTP. NEDC (old EU standard) was even more optimistic and has been replaced by WLTP since 2017.
Frequently Asked Questions about EV Range
How many km does an EV really drive?
In summer typically 80–90 % of WLTP. In winter at temperatures below −5 °C range can drop to 60–75 % of WLTP. Air conditioning, heating and driving style have a major impact. Our calculator therefore also shows a winter estimate.
How do standards affect EV choice?
When comparing cars with different standards, always convert values to the same base (preferably WLTP or EPA). A car with 600 km CLTC corresponds to approximately 508 km WLTP or 371 km EPA.
How to increase real EV range?
Key tips: preheat the battery in the garage in winter, keep charge at 20–80 %, drive economically (no harsh braking), use energy recuperation. On the motorway at 130 km/h consumption increases by 30–50 % compared to the standard.
Why do different models in the same category vary in range?
Battery capacity, aerodynamic drag, vehicle weight, tyre type and motor efficiency all play a role. A compact hatchback consumes 14–16 kWh/100 km, while a large EV SUV 20–25 kWh/100 km.
Conversion coefficients are indicative average values. Actual range depends on the specific vehicle, temperature and driving style.
